Appfication filed May 29,

To all whom it may concern Be it known that I, CHARLES RAUB, a citizen of the United States, residing at Cleveland, in thecounty of Cuyahoga and State of Ohio, have invented a certain new andand result in a marked convenience in the to switch boxes and manner-.of securing theears in place. A"

further object of theinvention is-to provide af'securin :me'ans of'this' character'which will enab e thesaid ears to with their securing] flanges arranged flush with the ends of' the-boxe's' or spaced there-' from,;accord ing',t o.the installation to which jects in and through thefconstruction and. arrangement'ofparts shown the drawings forming apart hereof, where1n Fig.1 repre sents a plan viewof a box embodying my invention; Fig.' 2a side elevation of the box; 3 an end levation of the same; Fig. 4 a detail in perspective of'one "end of such box and of the ear Fig. 5 a detail in plan, Fig. 6 a detail in end elevation, and Fig. 7 a detail in side elevation, of a portion of a box having a. modified'form of m invenlion applied thereto; Fig. 8 a detai in perspective of one end of the boxand the ear shown in Figs. 54'; and'FigsL9, 10 and It are views, corresponding to Figs. 5, 6 and 8, respectively, of astill further modification of the invention} Deseribing the parts by reference charac-- ters and with particular reference to Figs. 1-4 inclusive, 1 denotes the bottom, 2 the ends, and 3 the sides of a switch box of ordinary or standard construction. In the box shown in Figs. 1-4 inclusive, the sides are shown as secured rigidly to the ends, though they may be detachable, it being immaterial for the purpose of my invention whether or not the sides be easily removable. Projecting laterally from the upper end of each of the ends 2 are central lugs 4 having each an aperture for a screw 5 by which the switch object to provide a box he applied either the'box is to beapplied. I secure these obswrrcrr BOX.

assembly may be secured to the open end of the box.

In each end 2 there are provided a pair of slots 6. The centers of these slots are preferably equidistant from the screw 5 and the slots are adapted to receive hooked lugs projecting from the ears, one of which will now be described. Each ear comprises a flange 7 having apertures 8 for the reception of the screws by which thebox will be se-' cured to its support. Projecting from. 'each inner end of the flange 7 is a bearing plate 9, 9. One of these bearing plates, 9, is provided with a hooked lug 10 at its inner end and the other plate, 9, with a similarhooked lug 10 which is conveniently struck from the central portion of such plate. These hooked lugs'are adapted to be inserted into the slots 6, and the bearing plate 9" is provided with an inward extension ll having a projection 12 extending laterally therefrom. The slots 6 and the lugs 10 and 10 are so arranged that, when the lugs areinserted into the slots and the ear moved into its assembled osition upon the endof the box, the lu s W1 1 be engaged firmly with the interior of such end and the projection 12 will be in position to be engaged by the screw 5 at that end of the bog. v

By locating the lu s 10 a d 10 at substantially the midheig ht of the plates 9 and 9, the ears may be arranged with their flanges 7 flush with the open end of the box, as shown at the top of Figs. 1 and 2, or with their flanges below such open end, as shown at the bottom of Figs. 1 and 2. In either position, the screw can engage the projection 12 and serve the double function of securing the cover in place and anchoring the ear to the eiid of the box. In all other constructions with which I am familiar, two screws in addition to the screw 5 are employed for the purpose of anchoring each ear to a box. By my construction, no screws additional to the screws 5 are necessary and the expense of these additional screws is avoided as well as the equipment and labor necessary for tapping holes for such screws. The lugs 10 and 10 and the slots for the same are produced by asimple stamping operation, and the ears are no more expensive of production than those ordinarily employed.

The plates 9 and 9 cover the slots 6 when the ears are in place;:1nd the lugs are preferits support.

, top thereof with a. slotably slightly inclined a-wa. .from their respecti veplates to-zic'coinmo ate slight ymri'a: tions in the thickness of the end walls of the boxes and to facilitate their insertion into the slots.

"l-n-"Figs-s-s inclusive, there is shown a. modification of my invention, wherein the parts 1-5 inclusive are identical in construction with the like designated parts on Figs. l'l except that, at least'one of'tlie sii'les 3 is shown as removabhv secmtedtc the endsl as. by nieens of one or more screws 13 :i'dz ited each to extend thro "h aslot in, the si( e ,of the. box and threadiiil. into: ailing 14 carried by aside cfQthc' end adjacent .tosnch box side. .The other sidccfthe box may be per manentlysecured to.tl1e cniis..

In Fig. 7 one side of-the box is removed, showing the lug adjacentthereto in position to be engagcdby the said plate when the ear is positioned upon the end plate.

In Figs; 9-11 inclusive there is shown a still further modification o'ftlie invention wherein the parts 1-5 inclusive and 13, 1-1 are identical with the like designated parts in Figs. 5-8.
